Thermal Physics

Length and Time: Understanding units of measurement, conversions, and applications in physics problems.
Mass and Weight:
- Mass is the amount of matter in an object (measured in kg).
- Weight is the force exerted by gravity on an object (Weight = mass × gravitational acceleration).
Volume and Density:
- Volume is the amount of space occupied by an object (measured in m³, cm³, etc).
- Density is the mass per unit volume (Density = Mass/Volume, measured in kg/m³).
Speed, Velocity, and Acceleration:
- Speed is the distance traveled per unit time.
- Velocity is speed in a specified direction (vector quantity).
- Acceleration is the rate of change of velocity (Acceleration = (final velocity - initial velocity) / time).
Forces and Newton's Laws:
- Understand the basic forces acting on objects and how they apply to Newton's laws of motion.
Simple Machines: Principles of levers, pulleys, and inclined planes; mechanical advantage and efficiency.
Energy, Work, and Power:
- Work done is force × distance in the direction of the force.
- Energy can change forms but is conserved (law of conservation of energy).
- Power is the rate at which work is done (Power = Work/Time).

Kinetic Theory of Matter: Understand the relationship between temperature and kinetic energy.
Thermal Properties: How different materials absorb and transfer heat.
Transfer of Thermal Energy: Conduction, convection, and radiation.
- Conduction: Transfer of heat through a solid.
- Convection: Transfer of heat through fluids (liquid/gas) due to movement of the fluid.
- Radiation: Transfer of heat through electromagnetic waves.

Wave Motion: Understand the characteristics of waves, including amplitude, wavelength, frequency, and speed.
Properties of Sound: Sound waves as longitudinal waves and their speed in different media.
Light: Understanding the nature of light, reflection, refraction, and dispersion.
Electromagnetic Waves: The electromagnetic spectrum and applications.

Phenomenon of Magnetism: Properties of magnets, magnetic fields, and interactions with electric currents.
Electricity:
- Current is the flow of electric charge.
- Voltage is the energy per unit charge.
- Resistance is how strongly a material opposes the flow of electric current.
Electric Circuits: Understanding components in circuits including series and parallel connections, calculating total resistance, current, and power.
Practical Electricity: Connecting devices safely to power sources, measuring current and voltage.
Direct Current (d.c.) and Alternating Current (a.c.): Differences, advantages, and applications.

Atomic Structure: Understanding protons, neutrons, electrons, and isotopes.
Radioactivity: Types of radiation (alpha, beta, gamma), half-life, and applications.
Nuclear Reactions: How elements change during decay and the conservation of mass and energy in reactions.

Density Formula: $Density = \frac{Mass}{Volume}$
Force and Acceleration: $F = ma$
Work Done: $Work = Force \times Distance$
Power: $P = \frac{Work}{Time}$
Wave Equation: $v = f \lambda$ (Where $v$ is speed, $f$ is frequency, $\lambda$ is wavelength)
Ohm's Law: $V = IR$ (Where $V$ is voltage, $I$ is current, $R$ is resistance)
